" slowing global warming using fantastical technologies "

WASHINGTON — As international efforts to reduce greenhouse gas emissions
stall, schemes to slow global warming using fantastical technologies
once dismissed as a sideshow are getting serious consideration in
Washington.

Ships that spew salt into the air to block sunlight.
Mirrored satellites designed to bounce solar rays back into space.
Massive "reverse" power plants that would suck carbon from the
atmosphere. These are among the ideas the National Academy of Sciences
has charged a panel of some of the nation's top climate thinkers to
investigate. Several agencies requested the inquiry, including the CIA.

At the Jet Propulsion Laboratory in La Cañada Flintridge, scientists are modeling what such technologies might do to weather patterns. At the Pacific NorthwestNational Laboratory in Richland, Wash., a fund created by Microsoft founder Bill Gates — an enthusiast of research into climate engineering — helps bankroll another such effort.

"There is a level of
seriousness about these strategies that didn't exist a decade ago, when
it was considered just a game," said Ken Caldeira, a scientist with the
Carnegie Institution at Stanford University, who sits on the National Academy of Sciences panel. "Attitudes have changed dramatically."
Even as the research moves forward, many scientists and government officials worry about the risks of massive climate-control contraptions.

in which a ship sprays salt particles into the air to reflect sunlight
and slow global warming.
